Peace Across the Realm

Tang Yu was a doctor working across borders who, after an accidental injury, transmigrates into Great Tang and becomes its wastrel crown prince—indulgent, frivolous, and on the verge of being deposed. When a princess of Chu bullies the Tang court and tries to seize Tang territory through a literary contest, the Tang emperor is at a loss; Tang Yu uses his knowledge of modern literature to win a city for Tang. He then relies on his wit to keep the crown prince position.
